HVIPROVED FURNACE FOR CLARIFYING CIDER, 86C.

Specilication formi-ng part ot Letters Patent No. 44, 162, dated September I3, 18.74.

To @ZZ 1J/bont t may concern.:

Be it known that I, CHRISTOPHER Conv, of the town of Lima, county of La Grange, and State of Indiana, have invented a new and improved mode of constructing furnaces for clarifying and condensing cider, the juices of other fruits, and saecharine iiuids; and I do hereby declare that the following` is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in forming the upper portion of the side walls of the furnace, at or near ,its contact with its superineumbent evaporator, of gypsum or other materials of inferior heat conducting qualities, which will prevent or retard the conveyance ot' the heat to excess from said walls to the sides of said evaporator.

That others may be able to enjoy the beneiits of said invention, I submit the following statements.

The furnace on the main may be built after the most approved method now in common use, with ash-pit, gratebars, dre-doors and frame, well-adjusted Hue, chimney, damper, Ste., and with appropriate depth and width of wall. It may also be built of any of the Inaterials now in common use, except-at or near its connection with said pan, where the said gypsum, calcined or otherwise arranged, or other non-conducting material is used, in one, two, or more layers, to the completion of said furnace. These materials may be used in the form of bricks, blocks, or mortar, or in a pulverized state with suitable casings.

In the ordinary furnace, built of brick and Fig. 2 is a vertical longitudinal section of the same with the pan removed, this view be ing made on a smaller scale.

b b are the portions made of brick or other materials, and c c the position ofthe non conducting substances.

In presenting this applieation for Letters Patent, I do not claim any particular form of furnace; but

I do claim as my inventionrlhe formation ot' furnaces for clarifying or condensing the juices ot apples and other fruits, and also saccharine iluids,with one or more of the upper strata of 'their side walls made of gypsum, calcined or otherwise, or ol' other inferior or nonconducting materials, by which the excess of heat to the sides of the pan by contact with the walls of said furnace is prevented, substantially as and for the purposes herein set forth.
